Embodiment Construction
[0057] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0058] In the following, the dynamic optimization algorithm of firewall rule set based on statistical analysis and the dynamic optimization algorithm of firewall rule set based on heap structure are described through simulation experiments, and the relevant data are compared and analyzed.
[0059] (1) Experimental environment
[0060] The simulation experiment is carried out under the CentOS 6.3 operating system. The kernel version of the CentOS 6.3 operating system is Linux-2.6.32-279.19.1.el6.i686, the memory size is 512MB, and the compiler gcc version is gcc-4.4.4 .
[0061] The simulation tool is written in C language under Linux, and its main function is to realize the packet matching fun...
